Age: Between 160 and 145 million years ago.
Where in the world?: The Suining Formation of central China.
What sort of critter?: A sauropod dinosaur closely related to Mamenchisaurus.
Size: Approximately 50 feet long.
How much of the creature’s body is known?: A partial skull, the neck, parts of the back and tail, part of the hip, a toe, and assorted other fragments.
Claim to fame: Until now, all Late Jurassic sauropods from China were assigned to different species of Mamenchisaurus. Qijianglong, described by Lida Xing and colleagues, is the first sauropod from this time and place to definitely belong in a new genus. Among its distinguishing characteristics is a relatively shorter neck than Mamenchisaurus, indicating that China’s Jurassic sauropods came in a great diversity of shapes than previously known.
